Abstract

A new promising method for the preparation of crystalline 2D polymers based on tetra(4-pyridyl)porphyrin has been developed. Radical anion {H₂T(4-Py)P˙^-} species are used as the starting material. A new solid-state supramolecular array [{H₂T(4-Py)P}·{Tb^III(TMHD)₃}₂]·2.84C₆H₁₄ (1) in which porphyrin units are bridged with Tb^III ions to form a self-assembled 2D polymer has been obtained. The complex contains neutral porphyrin macrocycles, which is supported by optical and magnetic data. High-spin paramagnetic Tb^III ions are weakly antiferromagnetically coupled in accordance with rather long distances between them.
